I don’t know if this is the correct place to put this question so moderator please don’t get mad. Lol
I have a 2012 Silverado 3500 he LML with a Allison auto and the speedometer is registering 3 miles over on the dash. Is there a way to fix this? Maybe cable or by a electronically adjustment of some sort with a hand held electrical OBD ?
I am using the Garmin Zumba out of my VMax motorcycle on the dash for the wife for now, but really got to fix it. Any help would be appreciated.
